INDEPENDENT vs. INTERNAL IT AUDIT
OBJECTIVE – An independent audit is usually performed either due to regulatory requirements or those of third parties wishing to enter in collaborative or supplier relations, an outsourcing partner, for example. Internal audits are usually mandated by management and are more focused on business operations and their continuity.
AUDITORS – An independent audit is carried out by an external team, while internally audits are performed by members of staff. While the independent auditor may provide a more “fair view” of the current state, the internal audit may reflect a business’s proprietary technological and organizational characteristics more closely, with in-depth findings.
REPORTING – Usually, the independent IT audit will result in the main report being in a format required by auditing standards, with a focus on whether the Information Security claims of the company give a true and fair view and comply with requirements. These reports, whether formal or not, are designed to provide a status snapshot, rather than go into detailed recommendations on how to make things better.
Internal audit should produce a tailored report about how the risks and objectives are being managed – with a focus on helping the business move forward. As such, internal audit reports are expect to contain recommendations for improvement of the organization’s Information Security.
